Duktape is an embeddable Javascript engine, with a focus on portability and compact footprint.

Duktape is easy to integrate into a C/C++ project: add duktape.c, duktape.h, and duk_config.h to your build, and use the Duktape API to call Ecmascript functions from C code and vice versa.

Main features:

• Embeddable, portable, compact
• Ecmascript E5/E5.1 compliant
• Khronos/ES6 TypedArray and Node.js Buffer bindings
• Built-in debugger
• Built-in regular expression engine
• Built-in Unicode support
• Minimal platform dependencies
• Combined reference counting and mark-and-sweep garbage collection with finalization
• Custom features like co-routines, built-in logging framework, and built-in CommonJS-based module loading framework
• Property virtualization using a subset of Ecmascript E6 Proxy object
• Bytecode dump/load for caching compiled functions
• Liberal license

See duktape.org for packaged end-user downloads and documentation. The end user downloads are also available from the duktape-releases repo as both binaries and in unpacked form as git tags. Snapshot builds from master are available in duktape.org/snapshots.

This repository is intended for Duktape developers only, and contains Duktape internals: test cases, internal documentation, sources for the duktape.org web site, etc.

Current branch policy: the "master" branch is used for active development, other branches are frequently rebased feature branches (so you should not fork off them), and tags are used for releases. Master is quite stable, but may be broken from time to time so use it with care.

When embedding Duktape in your application you should use the packaged source distributables available from duktape.org/download.html. See duktape.org/guide.html#gettingstarted for the basics.

Automatically generated bleeding edge snapshots from master are available at duktape.org/snapshots.

You can also clone this repository, make modifications, and build a source distributable on Linux, OSX, and Windows using python util/make_dist.py.

If you intend to change Duktape internals and want to rebuild the source distributable in Linux, OSX, or Windows:

# Linux; can often install from packages or using 'pip'
$ sudo apt-get install python python-yaml
$ python util/make_dist.py

# OSX
# Install Python 2.7.x
$ pip install PyYAML
$ python util/make_dist.py

# Windows
; Install Python 2.7.x from python.org, and add it to PATH
> pip install PyYAML
> python util\make_dist.py

The source distributable directory will be in dist/.

For platform specific notes see http://wiki.duktape.org/DevelopmentSetup.html.

Other development stuff, such as building the website and running test cases, is based on a Makefile intended for Linux only. See detailed instructions in http://wiki.duktape.org/DevelopmentSetup.html.
